The telescope was parked for maintenance pointing to the zenith. Three projectors (operated by Pod Bluman’s team) were used to wrap light around the complex structure supporting the 76-metre diameter bowl of the telescope. The patterns only gradually evolved – often seeming static at first glance. But look away and then back again and the appearance was radically different. This short clip is speeded up by a factor 8 to show the changes more clearly.

Here’s a much longer, far more professionally produced, and beautiful timelapse of the installation from Kris Williams.
